Ethereum Foundation Launches Universal Ethereum Signer App

The Ethereum Foundation has launched the Universal Ethereum Signer app on the Passport Prime hardware device, which runs on the KeyOS operating system and is currently in the testing phase. The app was developed with funding from the Ethereum Foundation by Nicolas Bacca, co-founder of Ledger and current CEO of ZKnox. It allows users to review and sign Ethereum transactions on isolated hardware without having to expose their private keys to a mobile phone or computer. This marks the first time that Passport Prime users can utilize a third-party app as a dedicated signer for Ethereum transactions.
